Self-EDID Programming Procedure
The graphic source equipment generally requires display information (EDID). It contains
resolution and timing information of the display.
OMVC-200 supports Self-EDID programming for DVI and VGA inputs. It is the procedure
that reads the EDID from the display and stores it in the EEPROM of the converter. We
highly recommend do Self-EDID once when you install your system with OMVC-200 for the
first time.
Follow the steps below to do it correctly.
Note1:
If you know that EDID is not required by the user
’s source, Self-EDID
programming is not necessary.
Note2: The default EDID in factory ship-out is programmed in the VESA standard of
WUXGA (1920x1200), 60Hz.
Step 1
Connect 5V power adapter to turn OMVC-200.
Step 2
Power LED (Blue) will be turned ON.
Step 3
Push the EDID button on the rear side of converter with a narrow pin. Then, status
LED (Blue) will blink 3 times and turned ON.
Note 3: Push the DVI EDID button for DVI input or VGA EDID for VGA input.
Step 4
Connect the
DVI IN
port on the front side of converter to
the DVI input port of
display
over DVI cable.
Then the status LED will begin to blink rapidly. It indicates
reading the EDID from the display and storing it in the EEPROM. After 8~10 sec
blinking, the status LED will be turned OFF and it indicates completion of all
procedure.
Note 4: Connect VGA IN to the VGA input port of display for VGA input.
Step 5
Disconnect the converter from the display.
1-5 Self-EDID Programming Procedure
Troubleshooting
The display shows only black screen.
- Ensure that all plugs and jacks used by external power supplies (both
Opticis and others) are firmly connected. Ensure that the Power and status
LED ON.
- Ensure that the video ports are firmly plugged in to the sources and display.
- Ensure that the converter and receiver modules plugged correctly to the
sources and display, respectively.
- Check if the sources and display are powered on and properly booted.
Screen is distorted or displays noises.
- Check if the graphic resolution is properly set. Go to the display properties of
Windows and tap the settings.
- Ensure that the resolution sets less than WUXGA (1920x1200) at 60Hz
refresh ratio.
- Reset the system. Disconnect and reconnect the optical fiber or 5V power
adapters.
Maintenance
No special maintenance is required for the converter and power adapters.
Ensure that the converter and power adapters are stored or used in a benign
environment free from liquid or dirt contamination.
There are no user serviceable parts. Refer all service and repair issues to
Opticis.
